A system uses facial recognition to exclude persons of interest (e.g., “undesirables”) from events and/or venues. Such a system can include a combination of cameras, edge processing devices, and servers that are in communications coupling (e.g., via a network) and that are on premise and/or in the cloud to recognize such persons of interest (POI) and interdict and prevent such POI from entering, traversing, and/or attending (collectively, “entering”) such venues or events.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The system of claim 1, wherein each edge computing device executes multiple software modules that together perform facial detection.
3. The system of claim 2, wherein the multiple software modules include a face detection module that detects facial images in an image frame and that assigns each face a unique ID.
4. The system of claim 3, wherein the multiple software modules a face tracking module that tracks each face detected by the face detection module from frame to frame in the video stream and that recognizes that the face is either the same one or new entrant into the frame.
5. The system claim 2, wherein each edge detection device normalizes facial images to a preselected size.
6. The system of claim 2, wherein the multiple software modules include a face recognizer module to converting each face in the stream of images to a vector and to find a degree of similarity between each such vector and the downloaded embeddings.
7. The system of claim 2, wherein each edge detection device initializes a module to generate a match signal for facial images for which the degree of similarity is above that threshold.
9. An edge computing-based method according to claim 8, comprising transmitting to one or more handheld devices a facial image for which a match signal was generated.
10. An edge computing-based method of claim 9, comprising transmitting to the one or more handheld devices the degree of similarity on which the match signal was based.
11. The edge computing-based method of claim 8, wherein the downloading step includes downloading with the embeddings an indication of an algorithm by which they were generated.
12. The edge computing-based method of claim 11, wherein subsequent to a change in the algorithm the changed algorithm is downloaded to the edge computing device before the embeddings are downloaded.
